Who knew science -- not scifi, but actual science -- could be this cool? Probably scientists. And anyone who paid attention in science class. Never mind. Whether or not you loved science as a subject (and whether or not you are crushed that one of the few women on the show got eliminated last week, sniff), "The Big Brain Theory: Real Genius" is all about building cool stuff to rigorous standards, then trying to blow it up, set it on fire or destroy it in some other way. Who doesn't love blowing stuff up? Don't answer that.

Ricky Gervais isn't normally associated with semi-cuddly characters, but he takes a turn toward the sort of lovable with "Derek," which makes its Netflix debut Sept. 12 at 12:01 a.m. PT. All seven 30-minute episodes will be available at launch.

Want a second helping of "Catfish"? Apparently MTV has decided people want exactly that, because the network today announced that "Catfish: The TV Show" will return for a supersized 16-episode second season on Tuesday, June 25 at 10:00 p.m. This season everything is apparently elevated: the catfish are more sophisticated, the investigations are deeper, and the stakes are higher.

Tonight was the performance finale of "Dancing with the Stars" (the results show is Tues. at 9:00 p.m.), and I'll admit I didn't see much reason to watch, at least not closely. Though Zendaya dropped the ball with last week's routine, she's been the one to beat since week one. Long limbed and naturally gifted, she was certain to get to the finale and a lock to win.

The revolving door over at "The X Factor" might be pausing long enough to welcome in a new pair of judges. Kelly Rowland and Mexican pop star Paulina Rubio are the two names currently being bandied about as the most likely to fill the shoes of exiting judges Britney Spears and L.A. Reid. It seems Simon Cowell and the rest of the gang have decided once again that previous experience may be, if not necessary, helpful.

I was going to make some "Clone Wars" jokes, or maybe rehash some Cheech and Chong material, but given the way this week's episode of "Orphan Black" ended I'm not much in the mood for humor, are you? It was an awful, sour note on which to end and one that didn't entirely make sense, but one that I'm sure will reveal more strange layers once Sarah gets to the hospital.

Welcome to Reality TV Roundup -- a quick look at some of the reality TV-centric stories that have recently popped up across the fine, old Interwebs. Click away, my couch potato friends. But before you do...

SPOILER ALERT! SPOILER ALERT! SPOILER ALERT! One more time: SPOILER ALERT. If you watch any competition shows, the latest elimination for each show is probably revealed in the text below. The hope is that, if you missed this week's program and would rather clear out your DVR than watch the episode, you can get a quick hit here. But don't come crying to me if you find out something you didn't want to know. You've been warned. Also note: lots of non-competition reality info lurks below, too.

I suspected Penn Jillette was going to make the finals of "All-Star Celebrity Apprentice." No, I'm definitely not psychic. I'm not deeply in tune with the production, or worse, Donald Trump. But I had a feeling before the show even began that the magician who makes up half of Penn & Teller might go a little further on the franchise this time around.
